What Is Hydrogenated Castor Oil?
Hydrogenated castor oil is the oil extracted from castor (Ricinus communis) beans that has gone through the process of hydrogenation, which is adding hydrogen to a non-hydrogen compound. The result is the transformation of the original oil to a hard, waxy substance.
In cosmetics, hydrogenated castor oil serves many functions, including as an emollient, surfactant, occlusive and skin-conditioning ingredient. Its occlusive properties help preserve skin’s water content, thus aiding in moisturization.
The independent Cosmetic Ingredient Review panel has found it safe as used in cosmetics.
Hydrogenated castor oil is used in amounts ranging from 0.0003–39%. The largest concentration of usage is in eyeliners since it helps such products maintain a hard consistency that still applies smoothly.
